In 1931, during his time in London, Clare was given 'unrestricted access' to Mahatima Gandhi in order to execute his portrait. According to Gombrich, Gandhi was so pleased with the final result 'that he took hold of her brush and signed his name in oil colour',

This is the finest in a series of portraits that Winsten made of
Gandhi when she made his acquaintance in Hampstead during Gandhi's celebrated trip to England in 1931. Unlike so many portraits of Gandhi which were taken from photographs Winsten had the privilege of meeting Gandhi in person.

My parents life-time active involvement in social, humanitarian causes,
as well as the arts, brought them into touch with likeminded people
from many spheres. This affinity produced portraits of, among others,
D.H.Lawrence, Montessori, Catherine Lonsdale, Mahatma Gandhi, Bernard
Shaw.... My parents first met Mahatma Gandhi in the 1930s when living at
Hampstead (and this) led to a remarkable series of paintings and
drawings. There was such an empathy between them that Clare was invited
to be there .....whenever she wanted.
